Samsung just took a load of code and dumped it on the company's open source repository this afternoon, a la the Galaxy Tab Pro 8.4 in both Wi-Fi and LTE trims. There are a total of 5 kernel source files here, 2 for North American Wi-Fi variants (SM-T320_NA), 2 for global Wi-Fi variants (SM-T320), and one for the global LTE variant (SM-T325).

This follows the release of kernel source code for both the Tab Pro 10.1 and Note Pro 12.2 a month ago. The Tab Pro 12.2 remains the only one of the new Pro-level Samsung tablets without published kernel source at this point, though that's likely because it's not actually available for purchase until next week.
